Received new 370 Stroker engine. Installed on my -8A and made three flights .... all lasting five minutes as the oil temp never stopped rising. Landed at 230 but did not keep flying to see where it would end up. Removed engine when could not find the problem and put original back on.
Drained oil and in only 15 minutes it was already dark. Would assume excessive blow by? Pulled cylinders one by one to inspect for broken rings or scuffed piston. Cylinders are 9:6:1 steel. Nothing!
The oil cooler is the big cooler for the -10. Keeps temps in the 170s on the current 0-360.
Shop said check the vernatherm. But I am using the same one on the current 0-360 and it works like a charm. I am lost at what to look for. This is not a warranty situation so going back to mfg is not an option.
Several shops want to do a tear down but I am hesitant to do a tear down on an engine with only 15 minutes of flying. It was run in the dyno and was supposedly okay.
Thoughts?
